Re: Smoke damage
This is an appropriate slot to mention that one of my safety devices, the ubiquitous Smiths TS820 rotary timeswitch, has just failed in the ON position. I had blobbed it with a black marker previously as it was getting a little noisy (both acoustically and electrically) and the rotary manual adjustment mechanism had come to be less smooth than it should be, so in reality it should have been withdrawn from service a while ago.
This had potential to be a nasty one, as the OFF pegs are firmly in position and the ON/OFF manual override toggle in the corner is in the OFF position, but mains voltage is present on what should be the dead side of the appliance.
Contacts welded closed, perhaps.
